Movable forehead shield

ABSTRACT

The present invention relates to a forehead shield for a ballistic protective helmet, which is adapted to move with a visor of the protective helmet when the visor is opened and closed.

FIELD OF TECHNOLOGY

The present invention relates to a movable forehead shield for a ballistic protective helmet.

PRIOR ART

Ballistic protective helmets for protecting the head of its wearer have been known in the prior art for some time. These are used to protect against the direct impact of force by, for example, firearms fire or indirectly by, among other things, the impact on the head of the wearer by fragments and by the impact of cutting and stabbing weapons. Typically, this type of helmet is worn by special operations forces and increasingly also by patrol officers who arrive first on the scene (so-called “first responders”) with the objective of self-protection of the wearer.

The protective effect of such a helmet is achieved by stopping an impacting projectile (or fragment) and thus preventing penetration of the helmet towards the head of the wearer. In particular, this is intended to minimize the kinetic energy of the impacting objects, thus protecting the wearer from lethal effects. Titanium, aramid or polyethylene can be considered as typical materials from which the helmet dome of a ballistic protective helmet is made.

For further protection of the face, as well as in particular of the eyes of the wearer, it is possible to equip the helmet with a visor, which can be set up both permanently in front of the face and foldable up and down.

In order to provide additional protection especially for the anatomically sensitive forehead area of the wearer in the event of a frontal confrontation, e.g. in the event of frontal fire, but also in the event of an attack by means of cutting, stabbing or striking weapons, it is possible to equip ballistic protective helmets with a shield or a forehead shield in order to thereby obtain a further, reinforced protection zone in the area of the wearer's forehead. This is because it has been shown that very often attacks on police officers and emergency personnel are made from the front.

Typically, the forehead shield is attached to the helmet dome via a hook-and-loop fastener (Velcro) application. This method of attachment means that the shield can be detachably attached to the helmet dome in order to be able to supplement the protective effect of the ballistic helmet according to the situation (if necessary in conjunction with a visor). Situational conditions include, for example, an expected fire with a long weapon or other frontal impacts, which the wearer of the shield can face more directly. If the threat situation is classified as lower, the shield can be removed to reduce the weight of the helmet and thus increase the wearer's comfort.

However, the use of an additional shield regularly leads to disadvantages if the helmet is to be used together with a forehead shield and a visor. Due to the spatial expansion of the forehead shield, it is no longer possible to open it (e.g. by folding it up) with a conventional visor, as this is prevented by the spatial expansion of the forehead shield. This problem can be circumvented by designing the visor in such a way that it is able to slide over the forehead shield. Due to the visor's own weight and the extended lever arm, the torque acting on the helmet increases, which leads to an impairment of wearing comfort.

SUMMARY OF THE INVENTION

The invention is therefore based on the problem of improving the design of forehead shields known from the prior art to the effect that they can also be used in combination with a visor without the impairments to wearing comfort known from the prior art and without impairing or endangering the safety of police officers or emergency forces as a result of the way in which they are set up.

This problem is solved by a forehead shield for a ballistic protective helmet, which is arranged to move along with the visor of the protective helmet when the visor is opened and closed. According to the invention, the forehead shield is attached to the helmet in such a way that a visor can be moved together with the forehead shield. For this purpose, the forehead shield can in principle be attached to the helmet in a displaceable manner. This offers the advantage that a conventional visor can be used in this way, which thus offers the already known wearing comfort. A visor that slides over the forehead shield can be dispensed with. In addition, a time-consuming conversion of the helmet is no longer required situationally, since the desired functionality of opening and closing (or folding up and down) the visor is also made possible in joint use with the forehead shield.

The present disclosure describes several alternative ways in which the forehead shield can be slidably attached to a protective helmet. In this regard, the term “slidably” does not preclude the forehead shield or a portion thereof from rotating in addition to moving relative to the surface of a helmet dome when the forehead shield or a portion thereof is moved by a visor of the protective helmet. For example, the forehead shield or a part thereof, may be lifted from the helmet surface at the lower edge while the visor moves upward, i.e., out of the field of view. In addition to the shifting movement, a rotation then takes place. However, this is not excluded by the term “displaceable”.

In principle, the forehead shield can have a means for this purpose in order to attach the forehead shield to the protective helmet in a removable and displaceable manner. This offers the wearer of the protective helmet the possibility of adapting to the respective conditions of use and, in the event of an increased risk situation, to be able to fall back accordingly on additional ballistic protection, which can be made possible by the forehead shield. A removable forehead shield also offers the possibility of adding or retrofitting a forehead shield to existing helmets. Hook-and-loop fastener applications, for example, are the preferred method of attachment.

One way of forming the above-mentioned means is in the form of an enclosure which has means for pressing the forehead shield against an outer side of a helmet dome of the protective helmet. The enclosure may be arranged to receive a ballistic part of the forehead shield. This is to be understood as that part of the forehead shield to which the actual protective effect is assigned, e.g. in the case of bullet impact or the impact of cutting and stabbing weapons, and which may be made of a sufficiently resistant material, e.g. titanium or a fiber composite material. Basically, therefore, in the context of the present invention, a forehead shield is understood to mean not only this actual ballistic part, but, depending on the context, also further means, devices and elements which serve, for example, to attach the ballistic part to a protective helmet or to connect it to a visor. The aim of the enclosure is to attach the forehead shield to the helmet in a movable, yet sufficiently firm and stable manner. The enclosure may be, for example, a pocket that is adapted to receive the ballistic portion of the forehead shield and slide along the surface of the helmet dome. Alternatively, it may be an enclosure that encloses at least a portion of the edge of the ballistic portion.

Moreover, since the ballistic portion of the forehead shield is housed in an enclosure, no mechanical machining of the ballistic portion is necessary, which could be detrimental to the protective effect of the forehead shield. In principle, mechanical machining of the ballistic part of the forehead shield, such as drilling holes, reduce its protective effect.

The enclosure also comprises means for pressing the forehead shield against an outer side of a helmet dome of the protective helmet. On the one hand, this holds the forehead shield sufficiently firm against the helmet dome. On the other hand, it is ensured that at least a part of the forehead shield can lift off sufficiently from the helmet dome when the visor is opened. Such lifting can occur because the forehead shield is attached to a visor and this visor forms an increasing distance to the helmet dome during opening due to its non-spherical shape and/or an eccentric arrangement of the visor bearings. The means for pressing on the forehead shield compensate(s) accordingly for this lifting movement caused by the visor.

The enclosure may be adapted to be removably connected to a helmet dome. This allows the enclosure to be connected to the helmet if required, and the helmet can thus be worn with a forehead shield.

The enclosure may further be adapted to connect to and be removably adapted from a visor. The enclosure may be arranged to allow attachment to the helmet dome and/or visor. In this case, the fastening means is preferably formed by a hook-and-loop fastener application.

The means for pressing the forehead shield against an outer side of a helmet dome of the protective helmet may be at least one clamping element, which is arranged to be fastened to at least one visor bearing of the protective helmet. The tensioning element may be elastic, for example in the form of a rubber band, and may have a loop at at least one end which is adapted to be attached to a visor bearing of a helmet dome.

The tensioning element may be releasably connected to the enclosure. For example, the tensioning element may be connected to the enclosure by means of a hook-and-loop fastener application. In this way, the tensioning element can be separated from the enclosure and the enclosure can be attached to the protective helmet without the tensioning element, e.g. by means of a counterpart corresponding to the hook-and-loop fastener application. This fixes the forehead shield to the protective helmet and prevents it from moving. This may be desired, for example, if the protective helmet is worn without a visor.

The tensioning element may be secured closer to a side of the enclosure facing away from a visor of the protective helmet than to a side of the enclosure facing the visor. This arrangement allows for the aforementioned lift-off or rotational movement when the enclosure is displaced by a visor of the protective helmet: Due to the non-spherical shape of the protective helmet and/or an eccentric position of the visor bearings, a lift-off movement or rotation of the enclosure occurs at the lower edge of the enclosure against which the visor rests. This can be accommodated by fastening the tensioning element further away from the lower edge of the enclosure than from its upper edge.

The enclosure may be made of at least one flame-retardant material. In this way, burning of the enclosure and/or the tensioning element can be prevented in the event of firing, or at least delayed to such an extent that the forehead shield is held securely in position even in the event of subsequent firing.

In principle, the forehead shield according to the invention can have more than one tensioning element, e.g. two tensioning elements, which are arranged on opposite sides of the forehead shield or its ballistic part.

As previously explained, the inventors propose several alternative solutions for a slidable attachment of the forehead shield according to the invention to a helmet dome. According to another alternative, the means for removably and slidably attaching the forehead shield to the protective helmet is at least one rail which is adapted to be attached to the protective helmet and to slidably hold a portion of the protective shield. The rail may, for example, be adhered to the helmet surface or attached thereto by means of a hook-and-loop fastener application. The other part of the forehead shield, in particular the ballistic part, is then slidably held to the protective helmet by the rail and—similar to the enclosure mechanism described earlier—is displaced by a visor of the protective helmet during opening and closing.

The sliding part of the forehead shield may have a sliding element which is arranged to slide in the rail, which preferably has a T-slot. The sliding element may be arranged closer to a side of the ballistic part of the forehead shield facing away from the visor than to a side facing the visor. In this way, the aforementioned lifting or rotating movement of the movable part of the forehead shield can also occur with the rail mechanism described herein when the visor is opened.

The sliding element and the rail may be designed in such a way that the sliding part can be inserted into the rail. In this way, the movable part of the forehead shield, in particular the ballistic element, can be detachably and slidably connected to the helmet dome.

Independently of the fastening mechanism of the forehead shield to the helmet dome, the forehead shield may further comprise at least one visor fastening means for connecting the forehead shield to a visor of the protective helmet. Thus, the visor attachment means may be present in both the enclosure solution and the rail solution described herein. In the enclosure solution, the visor attachment means may be attached to the enclosure. The visor attachment means may be in the form of a hook and loop fastener application. A part of this application may be arranged on the visor, e.g. on a visor bracket, and the corresponding counterpart may be arranged on the forehead shield. The visor attachment means may be arranged to allow relative rotation between the visor and the forehead shield. Thus, the lift-off or rotational movement of the forehead shield already described can be supported when the visor is opened.

The forehead shield may in principle comprise a fixation means to fix the forehead shield to the protective helmet. In this way, the safety helmet can be worn with the forehead shield but without the visor. In this way, even without a visor, lifting or slipping of the forehead shield is prevented by the fixation means.

The visor fastening means and/or the fixation means may be a hook-and-loop fastener application. This allows the helmet to be easily converted between use with a visor and use without a visor: when the safety helmet is worn without a visor, the forehead shield can be easily fixed in place by the hook-and-loop fastener application. Once the protective helmet is again fitted with a visor, the hook-and-loop fastener application between the forehead shield and the protective helmet can be released and the forehead shield can be attached to the visor, e.g. to the visor bracket thereof, by means of another hook-and-loop fastener application to allow the forehead shield to move along with the visor, as described herein.

Another aspect of the present invention relates to a protective helmet comprising (a) a helmet dome; and (b) a forehead shield as described herein.

The protective helmet may further comprise at least one means cooperating with the fixation means of the forehead shield. For example, the means may be a hook-and-loop fastener application, wherein the hook portion or the loop portion may be disposed, for example, on the top surface of the helmet. The forehead shield can then be adequately fixed, as previously described, when the protective helmet is worn without a visor.

The fixation means may be designed to be fold-out. In this way, the fixation means is as unobtrusive as possible when the protective helmet with visor is worn.

The protective helmet may comprise a visor. As described above, the present invention can be used particularly advantageously with a protective helmet with a visor, since the front shield moves along with the visor during opening and closing.

The tensioning element may be formed by an elastic and tensionable material. In this way, on the one hand, the forehead shield can be easily pressed against the helmet surface and thus fits snugly against the helmet, and on the other hand, its flexibility allows the forehead shield to be lifted off the front edge when the visor is opened.

Still another aspect of the present invention relates to an enclosure for a ballistic element of a forehead shield for a ballistic protective helmet, the enclosure being adapted to receive the ballistic element and comprising means for pressing the ballistic element against an outer surface of a helmet dome of the protective helmet so that the ballistic element can be removably and slidably attached to the helmet dome. The advantages and further embodiments of such an enclosure have already been described in detail, so that reference is made thereto here to avoid repetition.

In principle, within the scope of the present invention, the helmet dome may be made of metal, fiber-reinforced plastic and/or a combination of both (hybrid helmet). For example, titanium is used as the metal and aramid and/or polyethylene fibers are used as the fiber-reinforced plastic. A hybrid helmet has been shown to be particularly resistant to fire from large caliber weapons.

In particular, the invention also allows helmets to be retrofitted with an additional forehead shield, whereby the protective helmet can be worn with or without a visor.

DETAILED DESCRIPTION OF PREFERRED EXEMPLARY EMBODIMENTS

FIGS. 1A, 1B, 2A and 2B show various views of a preferred embodiment of a forehead shield 3 according to the invention on a protective helmet 2. This is one of a number of ways in which the forehead shield 3 can be displaceably attached to the protective helmet 2, namely by means of an enclosure 9. The helmet 2 is a ballistic protective helmet, such as may typically be worn by emergency personnel, such as police or other emergency personnel, to protect themselves from firearm shot and/or force impacts of any kind from the outside. The embodiments of the present invention shown herein relate to ballistic protective helmets for special forces and police officers, but are not exclusively limited thereto, but are also applicable, for example, to protective helmets for military use.

The helmet dome 2 may be made of metal, of fiber-reinforced plastic and/or of a combination of both (hybrid helmet). The metal used is, for example, titanium and the fiber-reinforced plastic used is, for example, aramid and/or polyethylene fibers. The helmet dome 2 can be manufactured in a deep-drawing process, preferably from a one-piece titanium sheet, whereby a single-layer or multi-layer structure of the dome is possible. It is also possible to manufacture the helmet from steel or aluminum. Likewise, one or more layers of preferably a fiber composite material made of ultra high molecular weight polyethylene (UHMW-PE) are optionally considered, but are not limited to these. Further layers with aramid fibers can be added to this. In addition to the preferred embodiment, other fiber composites may also be considered in principle. A combination of materials is referred to as a hybrid. The helmet dome 2 can also be made entirely of plastics and/or fiber-reinforced plastics.

A forehead shield 3 is attached to the ballistic protective helmet 2, which can be worn in combination with a visor 4 (e.g. sight visor). The forehead shield 3, or the actual ballistic element of the forehead shield, is thereby preferably manufactured in such a way that it fulfills certain requirements of the VPAM (Vereinigung der Prüfstellen für angriffshemmende Materialien and Konstruktion—Association of Testing Bodies for Attack Resistant Materials and Construction) testing guideline, but is not limited thereto. By attaching the forehead shield 3, it is possible to additionally protect the frontal or forehead portion of the head 1 of a wearer of the protective helmet 2 from impacts directed frontally (or aimed at the forehead portion) against the wearer, as may be necessary, for example, with frontal fire, but also with the use of cutting and stabbing weapons. Also other, not mentioned attacks on the forehead part covered by the shield, can thus be parried without damaging effects on the wearer of the helmet. In the preferred embodiment, the forehead shield 3 is made of a fiber composite material of high molecular weight polyethylene fibers (UHMW-PE), but can in principle also be made of other materials, such as titanium, aluminum, steel or fiber-reinforced plastic, e.g., aramid fibers. By means of the forehead shield 3, it is thus possible to provide an additional, optional protective effect if this is required or desired for the situation.

In the embodiment example of FIGS. 1A, 1B, 2A and 2B, the forehead shield, or the actual ballistic element 3, is accommodated in an enclosure 9, which may have, for example, a rubber enclosure band and prevents the forehead shield, or the ballistic element 3, from slipping or falling out by means of an additional rubber band 10. In order to prevent unintentional movement of the forehead shield/ballistic element 3, the forehead shield/ballistic element 3 is pressed against the surface of the helmet 2 by a tensioning element 8, which may be set up, for example, as a rubber band with a tab.

In addition to a rubber band as well as the tensioning element 8, it is also possible to realize the enclosure 9 in another embodiment, as can be achieved, for example, by a pocket-like enclosure which can completely or also only partially comprise and thus enclose the forehead shield or the ballistic element 3. The enclosure itself can, in addition to a rubber enclosure band, also have other constructions such as a textile element. Furthermore, a metallic embodiment of the enclosure is also conceivable, for example as a bent sheet metal part, in which the end plate is fastened, for example, by snap fasteners or a clip connection, the possibility of embodiments not being limited to the embodiments indicated.

Importantly, in the context of the present invention, the enclosure 9 and thus the forehead shield received therein or the actual ballistic element 3 is movable along the surface of the helmet dome 2 to allow a visor 4 attached to the helmet 2 to be moved up and down. In a preferred embodiment, the visor 4 is set up as an all-plastic visor (sight visor) according to VPAM2/VPAM3, although other types of visors can also be used with the disclosure according to the invention. The visor 4 may further be held by a visor bracket 5 and connected thereto to the rest of the protective helmet 2. The visor bracket 5 may be rotatably connected to the protective helmet. This can be achieved by laterally, on both sides of the protective helmet, mounted corresponding bearings 6 (e.g. visor bearings) around which the visor bracket 5 can be rotatably mounted/fixed. The bearings 6 are thereby preferably attached to the helmet 2 in such a way that these are realized on opposite sides. However, the present invention is not limited to this form of attachment.

In a preferred embodiment, the bearing 6 thereby provides at least one tab location so that the visor bracket 5 can assume different angles relative to the vertical axis of the wearer. This offers in particular the advantage that the visor 4 can be opened and the opened visor position can be locked and thus an undesired folding down of the visor, e.g. during a running movement of the wearer, can be prevented. Likewise, in a preferred embodiment, at least one further tab location is provided to stabilize the closed state of the visor 4. Possible embodiments of the tab locations are not limited to the configurations described above, but any other tab locations can be integrated into the bearing 6.

In a preferred embodiment, it is possible, by means of a hook-and-loop fastener application 7, to connect the visor bracket (and thus the visor 4) to the enclosure 9 (and thus the forehead shield or the ballistic element 3), although other attachment mechanisms are also possible. When the visor bracket 5 is rotated about the bearing 6, the visor 4 can thus be folded up or down, whereby the hook-and-loop fastener application 7 causes the forehead shield 3 to move along with the visor 4 as the forehead shield 3 slides on the surface of the helmet 2.

In a preferred embodiment, one or more of the helmet components helmet 2, protective shield or ballistic element 3, visor 4, visor bracket 5, bearing 6, hook-and-loop fastener applications 7, tensioning element 8, enclosure 9, and/or rubber band 10 can be made of one or more flame-retardant materials, such as leather, Nomex, Kermel, rubber, flame-retardant plastics according to UL94 V-0 and metals, in order to be able to increase the protective effect of the helmet accordingly.

The hook-and-loop fastener application 7 between the visor bracket 5 and the enclosure 9, can be arranged in such a way that a kind of hinge 11 results, which makes it possible to adjust an angle between the enclosure 9 as well as the visor bracket 5 (and the visor 4 connected thereto). The direction of rotation of the visor 4 may be from the head 1 of a wearer outwards (and vice versa).

In the context of the present invention, the protective helmet 2 may also be worn without a visor. In principle, static design forms are also conceivable, in which the forehead shield 3 is connected to the helmet dome 2, for example, by a further hook-and-loop fastener application 13. The forehead shield 3 can also be used as a retrofit item with respect to an already existing protective helmet, which has all the required fastening elements for accommodating the forehead shield, but can also be purchased in combination with a protective helmet as a kind of unit. In this case, the use of the forehead shield is possible both with enclosure 9 and without enclosure 9, whereby it is also possible to retrofit a protective helmet with an enclosure to accommodate a protective shield. The protective helmet, in combination with a movable forehead shield according to the invention (with or without enclosure), can thereby additionally be combined with a visor 4 (e.g. a sight visor), whereby the visor 4 can also be designed as an optional additional retrofit option. According to the invention, the retrofitted visor can also be set up with retrofitted forehead shield (with and without enclosure) as a unit movable on the surface of the helmet dome.

The at least one tensioning element 8 fulfills two relevant functions: Firstly, the tensioning element ensures that the enclosure 9 is pressed against the helmet dome 2. Furthermore, the at least one tensioning element 8 serves to enable a joint movement of the enclosure and visor over the helmet dome, whereby a lifting of the enclosure at its lower edge during the movement over the helmet dome surface, due to its non-spherical shape, is enabled. An elastic and tensionable material can be realized relatively easily, for example, by a rubber band or an elastic textile, e.g. based on Spandex. In a preferred embodiment, the tensioning element is thereby such that it has a loop-shaped structure 12 at at least one end, which can be used to hook it onto at least one bearing and thus, on the basis of the tensioning force, to press the forehead shield against the helmet dome with or without enclosure.

FIG. 3A shows a side view of a ballistic protective helmet 2 in a further preferred embodiment, in which the helmet 2 can be worn without a visor as well as the associated visor bracket. In this case, the forehead shield or its ballistic element 3 is also placed in an enclosure 9 and received by the latter. By means of a fleece 13, which is attached to the upper side of the helmet 2 (preferably by an adhesive connection), and via a fastening element 14 in the form of a hook-and-loop fastener pad attached to the fleece 13, the enclosure 9 is held in position. The fastening element 14, which may be connected to the enclosure 9, for example, via a strap, thereby protects the enclosure 9 from unintentional movement, such as slipping or falling down. In a preferred embodiment, the ballistic element 3 of the forehead shield can additionally be connected to the enclosure 9 by another fastening element 14, thereby preventing the ballistic element 3 from slipping or falling out of the enclosure 9. When wearing the protective helmet with visor 4, this retaining function is taken over by the hook-and-loop fastener application 7. By means of an additional hook-and-loop fastener application 16, which in a preferred embodiment is arranged to fold out, it is possible to establish an additional connection between the helmet 2 and the enclosure 9. For this purpose, in the preferred embodiment, the hook-and-loop fastener application 7 is connected to the hook-and-loop fastener application 16. This serves to prevent unintentional lifting and/or slipping of the enclosure 9, from the helmet 2.

FIG. 3B shows a front view of the ballistic protective helmet 2 of the further preferred embodiment of FIG. 3A, in which the protective helmet 2 is worn without a visor and only the ballistic element 3 of the forehead shield is attached to the helmet 2 in the enclosure 9 and is additionally held in place by the further fastening element 10. By means of the hook-and-loop fastener applications 7, 14, 15, 16, it is possible to prevent unintentional lifting and/or slipping of the enclosure 9.

FIG. 4 shows an alternative solution for a forehead shield which can be moved along with a visor. A rail structure 18 of the forehead shield is attached to the helmet dome 2, which in a preferred embodiment has a T-slot into which a movable part of the forehead shield is inserted. A corresponding recess 19 of the rail structure 17 allows the T-shaped sliding part 18 to be inserted. Via the rail structure 17, the movable part of the forehead shield, in particular its ballistic element, can thus be pulled forward to the visor bracket 5, to which the visor 4 is attached, and connected to it by means of the hook-and-loop fastener application 7. This rail structure 17 also allows the forehead shield 3 to move along the surface of the helmet dome 2. This alternative solution can also be used both with and without the visor. In this case, the rail structure can be permanently connected to the helmet dome (e.g. by direct bonding) or removably. In a removable attachment of the guide rail to the helmet dome, in a preferred embodiment a hook-and-loop fastener application can be used for temporary attachment. A stop for the T-shaped sliding part 18 can be provided on the side of the rail structure 17 facing the visor bracket 5, which serves in particular to prevent unintentional slipping of the forehead shield when the protective helmet 2 is worn without a visor. For this purpose, the hook-and-loop fastener applications 7 and 16 may be used for fixation.

In a further embodiment, a flexibly configured pair of guide rails, which can be attached to the helmet dome either permanently or removably, can also be used to movably mount the forehead shield. Plastics, flame-retardant plastics and/or impact resistant modified plastics according to UL94 V-0 as well as metals are particularly suitable for the mounting.
